SAFETY PRECAUTIONS
Tool operators and maintenance personnel must always
comply with the precautions given in this manual and on
the stickers and tags attached to the tool and hose.
These precautions are given for your safety. Review
them carefully before operating the tool and before
performing general maintenance or repairs.
Supervising personnel should develop additional
precautions relating to the specic work area and local
safety regulations. Place the added precautions in the
space provided in this manual.
The BR45 Hydraulic Breaker will provide safe and
dependable service if operated in accordance with the
instructions given in this manual. Read and understand
this manual and any stickers and tags attached to the
tool and hoses before operation. Failure to do so could
result in personal injury or equipment damage.
• Operator must start in a work area without
bystanders. The operator must be familiar with all
prohibited work areas such as excessive slopes and
dangerous terrain conditions.
• Establish a training program for all operators to
ensure safe operation.
• Do not operate the tool unless thoroughly trained or
under the supervision of an instructor.
• Always wear safety equipment such as goggles,
gloves, ear protection, head protection, breathing
protection and safety shoes at all times when
operating the tool.
• Do not inspect, carry or clean the tool while the
hydraulic power source is connected. Accidental
engagement of the tool can cause serious injury.
• Supply hoses must have a minimum working
pressure rating of 2500 psi/175 bar.
• Be sure all hose connections are tight.
• The hydraulic circuit control valve must be in the
“OFF” position when coupling or uncoupling the tool.
Wipe all couplers clean before connecting. Use only
lint-free cloths. Failure to do so may result in damage
to the quick couplers and cause overheating of the
hydraulic system.
• Do not operate the tool at oil temperatures above
140 °F/60 °C. Operation at higher oil temperatures
can cause operator discomfort and may damage the
tool. Never contact the tool bit, the bit can get hot.
• Do not operate a damaged, improperly adjusted or
incompletely assembled tool.
• Do not weld, cut with an acetylene torch or hardface the tool bit.
• To avoid personal injury or equipment damage,
all tool repair, maintenance and service must only
be performed by authorized and properly trained
personnel.
• Do not exceed the rated limits of the tool or use the
tool for applications beyond its design capacity.
• Always keep critical tool markings, such as labels
and warning stickers, legible.
• Always replace parts with replacement parts
recommended by STANLEY.
• Check fastener tightness often and before each use
daily.
• Never operate the tool if you cannot be sure that
underground utilities are not present.
• Do not wear loose tting clothing when operating the
tool.
• Warning: Use of this tool on certain materials could
generate dust potentially containing a variety of
hazardous substances such as asbestos, silica or
lead. Inhalation of dust containing these or other
hazardous substances could result in serious
injury, cancer or death. Protect yourself and those
around you. Research and understand the materials
you are cutting. Follow correct safety procedures
and comply with all applicable national, state or
provisional health and safety regulations relating to
them, including, if appropriate arranging for the safe
disposal of the materials by a qualied person.
• Warning: Hydraulic uid under pressure could
cause skin injection injury. If you are injured by
hydraulic uid, get medical attention immediately.
• Keep all body parts away from the working tool.
• When handling material or the tool bit, wear your
Personal Protection Equipment (PPE).
• Be observant of the hydraulic hoses lying about the
work area. They can be a tripping hazard.
• Always de-energize the hydraulic system when
changing a tool bit.
• Never use the tool in an explosive atmosphere.
Sparks could ignite explosive gas.
• Use proper lifting techniques when handling the tool.
Get help from a co-worker and do not over-reach.
• Use proper protection from falling or ying debris
and keep bystanders at a safe distance.
• Do not exceed the rated ow and pressure. See
Specications in this manual for correct ow rate
and pressure rating. Rapid failure of the internal
seals may result.

HOSE TYPES
The rated working pressure of the hydraulic hose must be equal to or higher than the relief valve setting on the
hydraulic system. There are three types of hydraulic hose that meet this requirement and are authorized for use with
STANLEY hydraulic tools. They are:
Certied non-conductive — constructed of thermoplastic or synthetic rubber inner tube, synthetic ber braid
reinforcement, and weather resistant thermoplastic or synthetic rubber cover. Hose labeled certied non-
conductive is the only hose authorized for use near electrical conductors.
Wire-braided (conductive) — constructed of synthetic rubber inner tube, single or double wire braid
reinforcement, and weather resistant synthetic rubber cover. This hose is conductive and must never be used
near electrical conductors.
Fabric-braided (not certied or labeled non-conductive) — constructed of thermoplastic or synthetic rubber
inner tube, synthetic ber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover.
This hose is not certied non-conductive and must never be used near electrical conductors.
HOSE SAFETY TAGS
To help ensure your safety, the following DANGER tags are attached to all hose purchased from STANLEY. DO
NOT REMOVE THESE TAGS.
If the information on a tag is illegible because of wear or damage, replace the tag immediately. A new tag may be
obtained from your STANLEY Distributor.

OPERATION
The recommended hose size is .500 inch/12 mm I.D. up
to 50 ft/15 m long and .625 inch/16 mm I.D. minimum up
to 100 ft/30 m.
PRE-OPERATION PROCEDURES
CHECK POWER SOURCE
1. Using a calibrated owmeter and pressure gauge,
check that the hydraulic power source develops a
ow of 7–9 GPM/26–34 LPM at 1500–2000 psi/105–
140 bar or 5–6 GPM /18–22 LPM at 1500–2000 psi
/105–140 bar.
2. Make certain the hydraulic power source is equipped
with a relief valve set to open at 2250 psi/155 bar
maximum.
INSTALL TOOL BIT
1. Rotate the latch on the breaker foot downward
(pointing away from the tool).
2. Insert the tool bit into the foot and pull the latch up to
lock the tool bit in place.
CONNECT HOSES
1. Wipe all hose couplers with a clean, lint-free cloth
before making connections.
2. Connect the hoses from the hydraulic power source
to the tool ttings or quick disconnects. It is a good
practice to connect return hoses rst and disconnect
them last to minimize or avoid trapped pressure
within the tool.
3. Observe ow indicators stamped on hose couplers
to ensure that uid ow is in the proper direction. The
female coupler on the tool hose is the inlet coupler.
4. Move the hydraulic circuit control valve to the ON
position to operate the tool.
NOTE:
If uncoupled hoses are left in the sun, pressure
increase within the hoses may make them difcult
to connect. When possible, connect the free ends of
the hoses together.
NOTE:
Partially depressing the trigger allows the tool to run
at slow speed. Slow-speed operation permits easier
starting of the tool bit into the work surface.
5. To start, break an opening (hole) in the center of
the surface. After making a hole, break portions
of the material into the original opening. For best
productivity, the breaking should be done around
the original hole.
The size of the broken material will vary with the
strength and thickness of the base material and the
amount of any reinforcement wire or rebar.
Harder material or more reinforcing wire or rebar will
require taking smaller bites. To determine the most
effective bite, start with 2 in. / 50 mm or smaller bites.
Bites can then be gradually increased until the
broken piece becomes too large, requiring increased
time to break off the piece.
Sticking of the tool bit occurs when too large a bite
is being taken and the tool bit hammers into the
material without the material fracturing. This causes
the tool bit to become trapped in the surrounding
material.
COLD WEATHER OPERATION
If the breaker is to be used during cold weather, preheat
the hydraulic uid at low engine speed. When using the
normally recommended uid, uid temperature should
be at or above 50 °F/10 °C (400 ssu/82 centistokes)
before use.
Damage to the hydraulic system or breaker can result
from use with uid that is too viscous or thick.
OPERATION PROCEDURES
1. Observe all safety precautions.
2. Install the appropriate tool bit for the job.
3. Place the bit rmly on the surface to be broken.
4. Squeeze the trigger to start the breaker. Adequate
down pressure is very important. When the tool bit
breaks through the obstruction or becomes bound,
release the trigger and reposition the tool bit.
